Abstract: This invention relates to a control system for regeneration of a water treatment system in which a water meter monitors water usage and mechanically drives a water volume wheel to an operative position to call for regeneration when a predetermined volume of water has been treated and then automatically resets itself. A timer wheel driven by a motor is included within the control system such that the timer wheel and the water volume wheel coact to activate the regeneration cycle mechanism at a predetermined time after a predetermined volume of water has passed through the water meter. The mechanism is adjustable relative to the water treating capacity of the treatment system and the condition of the water being treated so as to be able to vary the predetermined volume of water treated which will call for regeneration.

Abstract: This invention relates to an improved method of installing an elongated heater such as a cartridge heater in a molding member such as an injection molding manifold member. First, a bore is drilled into an elongated portion of the manifold member to extend generally parallel to the hot runner passage extending through it and a filler duct is drilled from the top to intersect the bore along its length. The cartridge heater is then inserted into the bore and a filler tube with a base is set on the top in alignment with the filler duct. A brazing paste is then applied around the base of the filler tube and around the terminal portions of the cartridge heater extending from the bore. The manifold member is then heated in a vacuum furnace which brazes the filler tube in position and seals the outer end of the duct against leakage. A slug of copper is then inserted into the filler tube and the manifold member is again heated in the vacuum furnace sufficiently to cast the conductive copper to fill the space around the cartridge heater. The filler tube is then machined off to produce the finished manifold member. The copper fuses to the outer casing of the cartridge heater and the bore and together with the elimination of the insulative air space around the cartridge heater substantially improves heat flow and reduces the formation of hot spots which cause the heating element to burn out. In another embodiment, a tubular heater having two terminal portions is installed in a heater plate of a thermosetting mold with the terminal portions extending at opposite ends of the heater plate.

Abstract: The direct-current motor comprises at least one field winding supplied intermittently with direct-current voltage in order to produce a driving torque by interaction with permanent-magnetic poles which rotate with respect to the winding. The electromotive force of induction produced in the winding by the relative rotation of the permanent-magnetic poles is detected by means of a voltage measurement during the time intervals which elapse when the winding is not energized. A low-speed signal is produced when the electromotive force is below a pre-established threshold in correlation with the desired speed-threshold value.
